What is 8/33 plus 2/3? (Answer: 10/11)

Exact Answer

==================================================
Problem: What is 8/33 plus 2/3?
Formula / Expression: 8/33 + 2/3
Final Answer: 10/11
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 33 is an exact multiple of 3 (3 × 11 = 33). The Least Common Denominator (LCD) is simply 33, meaning we only need to scale one fraction.
Working: LCD(33, 3) = 33

Step 2: Convert to Equivalent Fractions with Common Denominator 33
Multiply the numerator and denominator of 8/33 by 1, and multiply the numerator and denominator of 2/3 by 11 so both fractions share the common base 33.
Working: 8 × 1/33 × 1 = 8/33 and 2 × 11/3 × 11 = 22/33

Step 3: Add the Numerators
Now add the numerators (8 + 22 = 30) and keep the common denominator 33 unchanged.
Working: 8 + 22/33 = 30/33

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 30 and 33, which is 3. Divide both the numerator and denominator by 3.
Working: 30 ÷ 3/33 ÷ 3 = 10/11

Step 5: Decimal & Percentage Representation
Dividing the numerator 10 by denominator 11 produces a repeating decimal (approximately 0.909091, or 90.9091%).
Working: 10 ÷ 11 = 0.909091 (90.9091%)

Key Values:
- Simplified Fraction: 10/11
- Mixed Number Form: 10/11
- Decimal Value: 0.909091
- Percentage: 90.9091%
